# --description--

You should now center the cat head. 

Give the `.cat-head` element a position property set to `absolute`. Set a value of `0` for the `right`, `left`, `top`, `bottom` properties, then set its `margin` property on all sides to `auto`. That's one way to center an element vertically and horizontally using CSS positioning.

# --hints--

Your `.cat-head` selector should have a `position` property set to `absolute`. Make sure you add a semi-colon.

```js
assert(new __helpers.CSSHelp(document)?.getStyle('.cat-head')?.position === 'absolute')
```

Your `.cat-head` selector should have a `top` property set to `0`. Make sure you add a semi-colon.

```js
assert(new __helpers.CSSHelp(document)?.getStyle('.cat-head')?.top === '0px')
```

Your `.cat-head` selector should have a `left` property set to `0`. Make sure you add a semi-colon.

```js
assert(new __helpers.CSSHelp(document)?.getStyle('.cat-head')?.left === '0px')
```

Your `.cat-head` selector should have a `right` property set to `0`. Make sure you add a semi-colon.

```js
assert(new __helpers.CSSHelp(document)?.getStyle('.cat-head')?.right === '0px')
```

Your `.cat-head` selector should have a `bottom` property set to `0`. Make sure you add a semi-colon.

```js
assert(new __helpers.CSSHelp(document)?.getStyle('.cat-head')?.bottom === '0px')
```

Your `.cat-head` selector should have a `margin` property set to `auto`. Make sure you add a semi-colon.

```js
assert(new __helpers.CSSHelp(document)?.getStyle('.cat-head')?.margin === 'auto')
```
